Abstract
A nickel(II) complex with the newly synthesized dicarboxamide ligand [H2LBZ][(CF3SO3)Cl] was explored as a water oxidation catalysis. All the synthesized compounds were characterized by IR and NMR spectroscopy, thermogravimetry, and single-crystal XRD analysis. The superior kinetics of the water oxidation reaction in the presence of the Ni-II catalyst was shown by an enhanced current of 4535 mu A (pH 8) or 8900 mu A (pH 10) at an overpotential of 186 mV in a cyclic voltammogram. Controlled potential electrolysis demonstrated that the catalyst was stable during the water oxidation experiment. These results are akin to those for other reported nickel catalysts.
